Why this? void chop() throws InterruptedException{ tree.interact("Chop down"); sleep(random(300,400)); } You have no null checks. Change to this ; void chop() throws InterruptedException{ if(tree != null); if(tree.isVisible()); tree.interact("Chop down"); sleep(random(300,400)); } You got this but I prefer to check it again for nulls. if(tree != null) state = State.CHOP;
